I mean, WordPress.com lets you have "mature" blogs... just no porn.
It's a minor miracle that Blogger of all things is the only big boy blog platform where you can still post hard dong. (Especially since they
did try the Tumblr playbook of trying to ban porn, but even Google saw how asinine that would be so long after the fact. Google: 1, Verizon -29,238)
Like, imagine if you could straight up post amateur porn on YouTube, and it was totally cool as long as you marked your channel as AO.
That's kinda what the situation with Blogger is right now.
